Isla is a Scottish place name or a Spanish word that means “island.”
Isla, a Scottish river, an island (spelled Islay), and the red-haired actress Isla Fisher, who is married to Sacha Baron Cohen, are all named after the Spanish word for island. Isla is a common girls’ name in the United States, as well as in England, Wales, and Scotland, where she was born.
Eloise is a French and English variant of Heloise, which means “healthy; broad.”
To some, Eloise will always be remembered as the haughty young girl who caused havoc at the Plaza Hotel, but in the original version, Heloise was the beautiful and scholarly wife of the French philosopher Peter Abelard, who was respected for her devotion and piety.
